ADJUSTABLE FIXTURE-SUPPORT.

Specification of Letters Patent.

Patented June 4, 1907.

Application flied Dvmber 22, 1906. Serial No. 349,075.

.To all whom it may concern:

Be it known that lf, THEoDoEE CARL J. ANDERsEN, a citizen of the UnitedStates, and a resident of the city of New York, borough of the Bronx, in.the county and State of New York, have invented a new and ImprovedAdjustable Fixture Support, of which the following is a full, clear, andexact description.

This invention relates to fixtures suoli as used for supporting electriclights from a wall or ceiling.

The object of the invention is to produce an insulated support of simpleconstruction, which maybe readily adjusted so as to hold a fixture in aplurality ofv different positions.

The invention consists in the construction and combination of parts tobe more fully described hereinafter and particularly set forth in theclaims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in 'which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective showing the fixture at its point of attachmentto a wall; Fig. 2 is a vertical section taken through the fixture andFig. 3 is a cross section taken on the line 3--3 of Fig. 2.

Referring more particularly to the parts, l represents a socket which isadapted to be attached to a wall by means of suitable screws 2 orsimilar fastening devices, passing through lugs 3 which project beyondthe.

base of the socket, as indicated. The outer side of the socket is formedinto a chamber 4, which is of polygonal form and preferably octagonal asindicated. Within this chamber 4 there is received a skew socket 5, madeof fiber or other non-conducting material, which is of octagonal form soas to lit the interior of the chamber 4. In the outer side of this skewsocket 5 a chamber 6 is formed, upon an axis which is inclined withrespect to the axis of the main socket l, and this chamber 6 is also ofoctagonal form. In the skew socket there is received the octagon al head7 of a shank 8 which consists of a bolt, the outer extremity whereof isbent to one side, as indicated, the tip of the shank being provided withscrew threads 9, which facilitate the attachment of a tubular arm orfixture 10, in the manner shown. This tubular arm 10 is intended tocarry electric lamps electrically insulted from the fixtures support, orother devices, depending upon the purpose for which the fixture is used.

The shank 8 is held in position by means of a keeper l1, 'which keeperis simply an insulating washer cut on a skew as shown, and which lits inthe outer side of the skew socket 5, the inner face of the said washerbearing against the outer face of the head 7 and holding the same inposition. The skew washer or keeper l1 is provided with an opening 12through which the shankS extends, as indicated. The keeper is held inposition by a nut 13 which screws upon the outer portion of the socket1, and this nut is provided with an opening 14 through which the shank 8extends.

As illustrated in Figs. l and 2, the arm of the lixture is disposed in avertical plane. If it be desired to adjust the arm toward either side,the nut 13 will be unscrewed, and the skew socket 5 will be withdrawnfrom the chamber 4 and replaced after rotating the shank 8 in eitherdirection, depending upon the direction in which the arm 10 is to beprojected. if it is desired to reverse the position of the arm from thatindicated in Fig. 2, so that the arm will project upwardly instead ofdownwardly, it will be necessary to unscrew the nut 13 and reverse theposition of the skew socket 5, by rotating it through 180. Evidently,with this arrangement, the arm would project upwardly instead ofdownwardly. There are, of course, eight different positions in which theskew socket may be applied to the main socket, each of which gives adifferent position for the arm 10. lf further adjustment is desired,slightly different effects may be produced by applying the head 7 in thechamber 6 in different positions; thus, if it were desired to have thearm 1() project upwardly but not at such an inclination as to projectdownwardly, as illustrated in Fig. 2, the shank S will be withdrawn andthe head 7 will be applied in the chamber 6 in a reversed position. Inthis way the bend of the shank S counteracts adjustment, which is due tothe inclination of the skew socket, so that the arm l0 projects upwardlyat a reduced angle of inclination. By this simple construction, it willbe readily seen that a number of adjustments may be IOO made so as tosuit the support to special requirements.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

l. In a device of the class described, in combination, a main socketadapted to be attached to a support, a skew insulating socket mountedtherein and adapted to be applied thereto in a plurality of positions,and a shank mounted in said skew socket.

2. In a device of the class described, in combination, a main socketadapted to be attached to a support, an insulating skew socket mountedtherein and having a plurality of adjusted positions, a bent shankhaving a head received in said skew socket, and means for retaining`said head in said skew socket.

3. In a device of the class described, in combination, a main socketadapted to be attached to a support and having a chamber in the outerside thereof, of polygonal form, a molding skew socket fitting saidchamber and adapted to be applied therein in a plurality of adjustedangular positions, a shank having a head received in said socket, andmeans for retaining said shank in position.

4. In a device oi the class described, in combination, a main socketadapted to be attached to a support and having a polygonal chamber inthe outer side thereof, an insulating skew socket received in said mainsocket, fitting the same and adapted to be applied thereto in aplurality of adjusted angular positions, said skew socket having apolygonal chamber therein, a shank having a polygonal head received insaid skew socket, the said shank being bent a keeper received in saidskew socket and retaining said head therein, and a nut retaining saidkeeper.

In testimony whereof I have signed my name to this speeiiication in thepresence oi two subscribing witnesses.
